If you'd like to try whether it helps, just add hpet=disable to the kernel lines in /boot/grub/menu.lst:
For example:
title Ubuntu intrepid (development branch), kernel 2.6.27-4-generic root (hd0,2) kernel /boot/vmlinuz-2.6.27-4-generic root=UUID=75ffa061-25f6-44b8-ac61-07452816b281 ro quiet splash hpet=disable initrd /boot/initrd.img-2.6.27-4-generic quiet
Other details may vary in your setup, this is only an example.
